ACProtect is an application that allows you to protect Windows executable files against piracy,using public keys encryption algorithms (RSA) to create and verify the registration keys and unlock some RSA key locked code,it has embedded cryptor against dump and unpacker.it also has many anti debug tricks. And you can use it to create evaluation and trial application versions. with specialized API system, mutual communication between loader and application is also can be achieved.

Embedded Protector - You can specify the place in your application to embed the inner cryptor. With the embedded cryptor, your application can not be cracked even though the cracker know the original entry point (OEP) when rebuilding your Import table.

Code Replace - Acprotect will replace some of your program 's code with the same function code in the ACProtect codes,If the ACPrtect code are stripped ,then the codes replaced will not function normally.

Metamorph Engine - Metamorph decryption routines and several encrypted layers. The code being protected varies every time you protect your application

RSA 1024 License - With RSA keys system a cracker can not write a KeyGen (or KeyMaker) for your product without the RSA private key (the RSA private key is only in the author's hand). You may also specify some code to be locked by the RSA keys, the cracker won't have the proper "key.dat" on the proper machine, without it the protected code can not decrypt.

Mutual Communication - API system which allows communication between application and loader, loader can call some of the application's export function, and the application can call the function the protected system provided.
